Patented Nov. 25, 1947 STATES PATENT OFFICE APPARATUS FOR SAWING ORNAMENTAL STONES Claims.

This invention relates to an apparatus for sawing ornamental stones, glass, bricks, tiles, and many other similar materials.

An object of the invention is the provision of an apparatus for sawing various crystalline and other hard materials with a diamond saw blade in which the materials are held by a pair of jaws movable toward each other for clamping the materials in place, said jaws being slidable on sleeves mounted on guide rods for eliminating strain 'or stress when the jaws are holding uneven materials so that the jaws may freely slide on the rods.

Another object of the invention is the provision of an apparatus for sawing various crystalline and other hard materials with a diamond saw blade in which a pair of clamping jaws for the materials are so supported and coordinated that said jaws may be moved longitudinally toward or away from each other over the surface of a saw-cleaning fluid in a housing or as a unit for operatively positioning the material relatively to the saw when said jaws have been moved longitudinally into gripping relation with the material.

A further object of the invention is the provision of an apparatus for sawing various crystalline and other hard materials with a diamond saw blade mounted in a housing containing a saw-cleansing solution, the upper open end of the housing having an inturned peripheral flange'to prevent the solution from splashing over the edge, a slidably mounted material-clamping device located over the solution and movable adjacent a table which will collect waste matter and pieces cut from the material.

With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing. from the spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings:

Figure 1 is a plan view of an apparatus for sawing ornamental st6nes and other similar materials with the protective cover removed.

Figure 2 is a longitudinal vertical section taken along the line 22, Fig. 1.

Figure 3 is a transverse vertical section of the apparatus taken along the line 3-3, Fig. 1.

Referring more particularly to the drawings, I0 designates generally a housing formed of any suitable material and the housing has an open upper end. A table I 1 extends laterally from one side wall of the housing and has an upturned lip l2 for a purpose which will be presently explained. It will be noted that the other side wall and the two end walls also have an upturned lip or flange IS. A brace I4 is connected to the side wall 15 of the housing and to the under face of the table ll for aiding in supporting said table.

An inspection of Fig. 1 will show that a bearing I6 is bolted at I! to the side wall l5 and this bearing supports a shaft l8 which projects through the side wall I 5 above the level of a liquid IS in the housing M. A pulley 20 is secured to the outer end of the shaft l8 beyond the outer edge of the table II. A saw 2| is secured to the shaft [8 by a nut 22 at the inner end of the shaft so that the lower portion of the saw will be mersed in the liquid or solution l9. The pulley 2D is driven by a belt connected with a power,

plant so that the saw 2i will be revolved in the housing.

The diamond saw blade 2| is circular and is adapted to saw such rock specimens as ornamental stone, ceramic, glass, semi-precious materials such as agate, jasper, petrified wood, and many other non-metallic materials.

A carriage is provided for supporting the materials to be sawed and this carriage is mounted for reciprocation longitudinally of the tank or housing l3 and is adapted to be moved transversely of the tank for positioning the materials which are to be cut, in line with the circular saw 2|. The carriage is mounted on a pair of guide bars 25 which have their ends secured in the opposite side Walls of the tank l0 and adjacent the end walls of said tank. A block 26 is slidably mounted on one guide bar 25 while a block 21 is slidably mounted on the other guide bar. The block 25 is provided with an extension 28 while the block 21 is provided with an extension 29. A pair of rods 30 have their ends received by passages in the blocks 26 and 2'! adjacent the end walls of the tank and set screws 3| secure these rods to the blocks so that the rods 30 and the blocks form a carriage which is movable transversely of the tank l6.

A sleeve 32 is slidably mounted on each rod 30 and these sleeves are received by passages in jaws 33 and 34 so that these jaws are slidable on the sleeves with the sleeves being slidable on the rod 30. The opposite ends of the sleeves 32 are provided with flanges 35 to prevent the jaws from being displaced from said sleeves. The jaws 33 and 34 are provided with a coating of leather 36 so that the material which is gripped between the two jaws will not be broken since the jaws are formed of metal.

An operating rod 31 has a squared portion 38 projecting through an opening in an end wall of the tank m. The portion of the rod which is located within the tank is threaded into passages in the lower portion of the jaws 33 and 34. As shown in Fig. 1 one portion of the threads are left hand while the other portion contains right hand threads so that as the rod 3'! is operated by a crank 39 the jaws 33 and 34 will be moved toward or away from each other depending upon the rotation of said rod for gripping or releasing the work to be operated on.

A threaded rod 40 is received by a threaded passage in each of the extensions 28 and 29, the outer ends of these rods as ShOWn in Fig. 1 are mounted in bearings 4| in a side wall 42 of the tank l9. These threaded rods project through said side wall and a sprocket '43 is secured on each projecting end. A chain 44 is trained over the sprocket. A crank 45 is adaptably connected to the squared end 46 on one of the rods '40 for rotating b'oth rods simultaneously through the chain and the sprockets. When this happens the carriage supporting the jaws 33 and 34 are moved transversely of the tank 19 and these Ijaws will then position the workin line with the cutting edge of the circular saw 2i.

An 'arm 41 projects rearwardly of the jaw 33 as shown in Fig. 2 and is provided with a hand grip 48 in order to move the jaw back and forth when desired. The jaw 34'is provided with apassage '59 which receives one end of a cable This cable is trained over a pulley '52 carried by a bracket 53 projecting from an end wall 54 of the tank 59. A weight 55 is secured tothe free end of the cable '51. Since the jaws 33 and 34, when gripping a piece of work to be cut, arefree to slide along the rods 39 as a unit, the'weig'ht55 will pull the jaws toward the periphery of the revolving saw 2| and maintain the work in contact with said saw. This eliminates 'the necessity of having an operator in constant attendance during the sawing operation.

A spring clip 5'! is secured to the jaw 33 as shown in Figs. 1 and 2, and the end'of this clip is adapted to engage apin 58 projecting upwardly from the block 25 for maintaining the jaws adjacent the end wall 59 of the tank I0 and out of operative relation withthe saw 2|.

A pointer 69 is securedto the top of theblock 26 and this pointer moves over a'scale 6| on the upper end of the end wall 59. As the carriage is shifted transversely of the tank l9 and towards the saw 2!, the pointer 69 will indicate on the scale 6! the degree of thickness of the slicing desired.

A battle 63 is located near the periphery of the circular saw 2| to prevent liquid being splashed from the tank. The flanges "I2 and I3 aid in pre venting the liquid from splashing over the upper edges of said tank. The cover 54 is mounted-on the top of the tank to protect the operator from injury from the revolving mechanism of the saw.

A handle 35 is employed for raising the cover 64.

A door 55 is hinged at 8! on the front end ofthe cover and is provided with a knob 68 for raising the door so that the operator may view the work during operation without necessitating the raising of the cover.

The wall 59 is provided with an opening 10 through which the liquid or solution I9 in the container I0 is drained. A plug H normally closes said opening.

The operation of the device is as follows.

The tank In is partially filled with a cleansing or flushing solution in order to prevent the saw from clogging. This solution is usually kerosene with motor oil added, but in the case of sawing glass or quartz crystal the solution may be water in which is dissolved soda to prevent rusting. It will be noted from Fig. 2 that the lower end of the saw 2| dips into the solution and below the shaft is. The carriage including the clamp elements 33 and 34 together with the transverse guide rods 25 and the operating screws are also above the level of the liquid.

The cooperating jaws 33 and 34 are moved as a unit on the sleeves 32 toward the end wall 59 of the tank so that the spring clip 51 will engage the pin 58 to retain the laws in position.

Thelma'terialto be sawed is placed between the jaws 33' and 34 and between the leather facings of said jaws. The rod 3'! is then rotated by the crank 39 until the jaws firmly clamp the work between the facings 36.

The crank is then revolved in the proper direction so that the carriage containing jaws 3'3 and 34 is moved transversely of the tank until the pointer 69 indicates the proper cut on the scale 6 I. The saw 2| is then revolved after which the spring clip 51 is released from the pin 58 whence the weight will move the jaws and work clamped therebetween to the cutting edge of the saw nd will maintain the work in contact with the saw until the sawing operation has'been com- *pleted.

The lower edges of the clamps 33 and '34 are so formed that they will clear the inner end of the shaft I 8 together with the nut 22 so that the saw can come close to the adjacent ends of said jaws.
